| 摘 要： | 通过分别测定红毛丹果实各部分的厚度,并利用X射线图像测定射线强度,研究其X射线衰减系数,同时研究衰减系数与其密度的相关性,建立射线强度和厚度的回归方程以及果实的衰减系数与果实的果皮、果肉、果仁衰减系数的关系,为外形尺寸大小的分级奠定基础。 |
| 关 键 词： | 红毛丹 X 射线 衰减系数 |

| Abstract: | The thickness of the skin, flesh and kernel of rambutan fruit was measured by X-ray, and the beam intensity was determined by X-ray imaging to study its coefficient of attenuation and establish relationship between the attenuation coefficient and its density. A regression equation for X-ray intensity and thickness of various parts of the fruit was established as well as the attenuation coefficient relationship of the fruit with the skin, flesh, and kernel, which is provided for classification of fruit sizes. |
| Keywords: | rambutan X-ray attenuation coefficient |
